My brother's cam went bad, his dealer sold him one from a 500ho. According to the dealer, the only difference is a little longer duration. We will see how she moves. That 425 magnum was mine and it really moved out before.

 

Well the 425 is back together and he says it sounds good. I'll go give it a good run next weekend.

 

Now get you a carb off of a 500ho and a good clutch set up and you will really rock.

 

Holy cow that thing really goes now, bottom and mid range are strong.
